Hi,
I have a wheezing old Dell Latitude LM that I just upgraded to the
JAN24 current snapshot. Whenever I remove my 3com 3c589d PCMCIA nic,
the machine locks solid while emitting a very loud (continuous) beep.
When I suspend the machine & awaken it, everything works just dandy.
ep0 is initially not in the interfaces list (ifconfig -a), then the
card is recognized.
I suspect (and only suspect) that the problem might be that the system
is missing an interrupt & does not know that the nic has been removed.
I tried running in polling mode (eg, I didn't give pcic0 an irq in the
config file). When I remove a card in this configuration, the machine
locks solid (and doesn't beep).
The previous owner of this machine had it running under 2.2.blah-PAO &
removals/insertions worked, so I know it isn't the hardware. I've
included dmesg output & my config file.
Thanks in advance for any help..
Cheers,
Drew
